A Model Context Protocol (MCP) server that lets you manipulate Excel files without needing Microsoft Excel installed. Create, read, and modify Excel workbooks with your AI agent.
Features
- 📊 Excel Operations: Create, read, update workbooks and worksheets
- 📈 Data Manipulation: Formulas, formatting, charts, pivot tables, and Excel tables
- 🔍 Data Validation: Built-in validation for ranges, formulas, and data integrity
- 🎨 Formatting: Font styling, colors, borders, alignment, and conditional formatting
- 📋 Table Operations: Create and manage Excel tables with custom styling
- 📊 Chart Creation: Generate various chart types (line, bar, pie, scatter, etc.)
- 🔄 Pivot Tables: Create dynamic pivot tables for data analysis
- 🔧 Sheet Management: Copy, rename, delete worksheets with ease
- 🔌 Triple transport support: stdio, SSE (deprecated), and streamable HTTP
- 🌐 Remote & Local: Works both locally and as a remote service
Usage
The server supports three transport methods:
1. Stdio Transport (for local use)
uvx excel-mcp-server stdio
{
"mcpServers": {
"excel": {
"command": "uvx",
"args": ["excel-mcp-server", "stdio"]
}
}
}
2. SSE Transport (Server-Sent Events - Deprecated)
uvx excel-mcp-server sse
SSE transport connection:
{
"mcpServers": {
"excel": {
"url": "http://localhost:8000/sse",
}
}
}
3. Streamable HTTP Transport (Recommended for remote connections)
uvx excel-mcp-server streamable-http
Streamable HTTP transport connection:
{
"mcpServers": {
"excel": {
"url": "http://localhost:8000/mcp",
}
}
}
Environment Variables & File Path Handling
SSE and Streamable HTTP Transports
When running the server with the SSE or Streamable HTTP protocols, you must set the EXCEL_FILES_PATH environment variable on the server side. This variable tells the server where to read and write Excel files.
- If not set, it defaults to
./excel_files.
You can also set the FASTMCP_PORT environment variable to control the port the server listens on (default is 8017 if not set).
- Example (Windows PowerShell):
$env:EXCEL_FILES_PATH="E:\MyExcelFiles" $env:FASTMCP_PORT="8007" uvx excel-mcp-server streamable-http - Example (Linux/macOS):
EXCEL_FILES_PATH=/path/to/excel_files FASTMCP_PORT=8007 uvx excel-mcp-server streamable-http
Stdio Transport
When using the stdio protocol, the file path is provided with each tool call, so you do not need to set EXCEL_FILES_PATH on the server. The server will use the path sent by the client for each operation.
Available Tools
The server provides a comprehensive set of Excel manipulation tools. See TOOLS.md for complete documentation of all available tools.
